Good Day everyone, i am planning to redo my network with Nethserver 7. Planning on using it for DHCP, DNS, Firewall, Bandwidth Monitor, traffic Shaping, vpn and possibly also gonna try Active directory.

My main goal is to route all my lan traffic through my firewall by using port based vlans on my managed Switch blocking access between each users, as opposed to switches routing. I am sure this will put a heavy load on the firewall. I was wondering what hardware specifications i would need to accomplish this. the users will be accessing one database application from my db server. I have approximately 50 users and my hardware specs are as follows.

Would I be able to achieve Gigabit speeds between my user network and my server network though, that is my real fear. Afraid to sacrifice speed for added security of port based vlan. If there is a better route i would be happy to hear your feedback also. This is my first attempt at vlan and I am only going this route based on my limited knowledge from what i have researched.
